Data and Analysis

Measured Data

Angle of Elevation	45 degrees
Time Up	5.76 seconds
Time Down	4.67 seconds

Angle of elevation was measured from a point 50.m from the launch site, as illustrated by diagram below.

Height

Since tan(45) = height/baseline
height = baseline * tan(45)
height = 50.m * 1
height = 50.m

Average Ascent Velocity

D (height of rocket) = 50.m
T (time up) = 5.76s
V = ?

V = D/T
V = 50.m / 5.76s
V = 8.7m/s

Average Descent Velocity

D (height of rocket) = 50.m
T (time down) = 4.67s
V = ?

V = D/T
V = 50.m / 4.67s
V = 11m/s

Sources of Error

Non-vertical flight of rocket (caused by lateral wind, angle of launch pad into wind.) Invalidates baseline measurement, potentially large effect on calculated maximum height of rocket.

Additionally, the 50m baseline was not measured but simply paced out, casting further doubt as to its accuracy.

Measurement error: precise point / time of apogee is difficult to determine. Probably minor effects on measured values.
